ADJUSTABLE FLOW ATTACHMENT Filed u 5, 19:50 2 Sheets-Sheet 1 March 29, 1932. H. G. LANE ADJUSTABLE PLOW ATTACHMENT Filed Aug 5, 1930 2 Sheets-Sheet 2 its upper end provided with a wing nut 23, so that'by screwing up the nut, the two disks will be drawn to ether and clamped so as to hold the wings in their adjusted positions. By extendin the bolt up through the stock and having the nut at its upper end it is more accessible and the operation is easier in manipulating the parts to loosen the connection between the two disks to permit one to be adjusted relatively to the other to vary the set of the sweeps or scrapers. In Figure l of the drawings the upper end ofthe stock is shown as formed with a yoke 24 which forms a. seat or bearing for the win nut 23 in operating the clamping bolt. In Figure 8 of the drawings oppositely disposed ears'25- projecting from the upper part of the stock are employed for affording a seat for the wing adjusting nut, and a washer plate 26 may span and rest upon the ears as a bearing 'forthe nut. The operation ofthe parts mentioned is substanhall the same as illustrated in Figure 1 of the rawi In Figure 8 of the drawings, the forwar 1y extending arms 8 of the hollow stock fi instead of having perforations 10 in theirends for adjustment of the beam and stock in relation to each other, is formed with flmuate slots 27 for passage of bolt 9, and serrations or teeth 28 may be formed along the slotswith which will engage teeth'of washer plates 29, so that when an adjustment has been made and the nut of bolt 9 tightened, the parts willbc clamped in holding positions. In Figure l the stock arms 8 are shown as positioned outside of-the parallel bars 2 forming the plow beam and in Figure 8 the areshown as lying between the bars of t e beam but any other suitable disposition of the parts may be used. Nor is the invention limited to an particular form or construction of plow earn as the novel features may be employed regardless of the typeofplow beam employed, and this is true whatever manner of attaching the plow handlles is employed. 7 I

i FigurelO of the drawings a different form of 'plow stock is shown, but the lower face of the stock is formed with a boss correspondi substantially to the boss 15 of the form 0 stock shown in the other figures of the drawings and being below the seat 11 for the plow point.v In the form of Fig. 10 the disk 16 of one of the wings 17 fits in the v recess of the boss, and the meeting faces of the two disks 16 are formed with serrations 19. The clamping bolt 30 passes through the two disks 16 and its head 31 lies within the boss as illustrated and its threaded end is provided with nut 32 for tightening and clamping the parts in position. In this. formthe boss 15 is formed with a laterally disposed slot 33 for easy positioning of the bolt in assembling the parts. While this form possesses some of the structural features in the forms of Figs. 1 and 2, it is without the advantages resulting from having the clamping bolt extending from the boss at the base of the stock up to the top of the stock for manipulation as in the other forms.

It'is obvious from the foregoing description that the invention is not llmited to particular features of construction except as the same may be defined in the appended claims.

Having described my invention and set forth its merits what I claim is:

1. In combination with aplow stock formed with a boss on its under side, at its lower end, of wings formed at one end with disks fitting one upon the other, one disk bein seate against the end of said boss, a ho t passed through ithe disksand projecting from the lower end of the stock for looking together the stock and wings, and sweep or scraper blades secured to said wings.

2x111 combination with aplow stock formed with a boss on its under side, at its lower end, of wings formed at one end with disks having intermeshing toothed faces fitting one upon the other, one disk beingseated against the end of said boss, a bolt passed thro h the disks andboss at the lower end. of e stock for locking together the stock and wings, and sweep or scraper blades secured to said wings.

3. In combination with a plow stock formed n witha boss on its underside, at'its lower end, of radiall adjustable win lapp one upon the ot er, with one of t em seat ed on said boss, means consisting of a bolt passing through said boss and the win 3 foradjustably securing the wings to the Iower end of the stock, and sweep or scraper blades attached to the wings.

4. In combination with a plow stock, of superimposed disks rotatably mounted at the lower end of the stock and each provided with a wing for attachment of a sweep or scraper blade, a bolt connected with the disks and extending substantially the length of the stock, andmeans positioned adjacent the u per end of the stock and associated with t e bolt for clamping-the wings to the lower end of the stock.

5. In combination with aplow stock formed p 6. In combination with a plow stock of substantially tubular or hollow formation, of superimposed disks rotatably mounted. against the lower end of the stock and each provided with a wing for attachment -of a sweep or scraper blade, a bolt passing through the stock and connected at its lower end with posed disks rotatably mounted beneath the said disks,-and means connected with the upper end-ofthebolt for clamping the wings; to the lower end of the stock. v 7. Incombination with a plow stockformed 5 with 'a boss at its lower end, of-superim boss and each having a wing for attachment, of a sweep or scraper blade, one of said disks having dportion fitting in a recess formed 10 in the stock boss, and means for clamping the wings inndjusted' positions to the stock In testimony whereof I afii'x mysignature.
